The jack on my magsafe charger ripped off a few years ago and before that happened, it must have shorted something inside my macbook as it would not charge any battery afterwards with any new charger. The battery in the upper right corner showed up with an x, the light on the charger will go from a bright green to a dim green right when I put it in and since then the hard drive broke as well, which is why I haven't made much of an attempt to fix it. My question is, What's wrong inside the computer (i.e. logic board, battery connector) and what any of your opinions are. If I can fix it, what piece will I need to buy and would it be worth or should I just sell my macbook?
